From spreadsheet user to data literate in 30 days
Data literacy is the most portable skill in the modern workplace — and a month of evenings is genuinely enough for a working level.

Every team drowns in numbers, and the person who can turn them into a clear answer becomes quietly indispensable. You can reach that level in 30 focused days.
The 30-day path
- Week 1: spreadsheet fluency — pivots, lookups, cleaning messy exports.
- Week 2: asking better questions — averages vs medians, cohorts, why 'up 30%' can be meaningless.
- Week 3: one visualisation tool — charts that answer a question, not decorate a slide.
- Week 4: a real project — take a live question from your own job and answer it end to end.
The finish linePresent that week-4 project to your manager. It upgrades your reputation and your review in one move.
